php - TLS 1.2 在 cURL 中不起作用

Question

我在 curl 使用 TLS1.2 的 HTTPS url 时遇到问题，在我的 curl 操作中，我将登录数据发布到网站并将其保存在 cookiefile 中。我得到的错误信息是这样的

 error:14077438:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert internal error

我尝试将 VERIFYPEER 和 VERIFYHOST 设置为 0，但这似乎不起作用，有什么建议吗？

这是我正在使用的版本:

• OpenSSL 版本为 0.9.8b
• CURL 版本为 7.24.0
• PHP 是 5.3

代码如下:

$setuplogin = curl_init(); 
curl_setopt ($setuploginurl, CURLOPT_URL, $url); 
curl_setopt ($setuploginurl, CURLOPT_SSL_VERIFYPEER, 1); 
curl_setopt ($setuploginurl, CURLOPT_SSL_VERIFYHOST, 1);
curl_setopt ($setuploginurl, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, 'CURL_SSLVERSION_TLSv1_2');
curl_setopt ($setuploginurl, CURLOPT_POSTFIELDS, 'username=uname&password=pword&act=login&submit=Login');
curl_setopt ($setuploginurl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36"); 
curl_setopt (setuploginurl, CURLOPT_TIMEOUT, 60); 
curl_setopt ($setuploginurl, CURLOPT_COOKIESESSION, TRUE); 
curl_setopt ($setuploginurl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($setuploginurl,  CURLOPT_HEADER, 1);
curl_setopt ($setuploginurl,CURLOPT_ENCODING,"gzip");
curl_setopt ($setuploginurl, CURLOPT_POST, true);
curl_setopt ($setuploginurl, CURLOPT_COOKIEJAR, 'cookies.txt'); 
curl_setopt ($setuploginurl, CURLOPT_FRESH_CONNECT , 1);

$loginp= curl_exec($setuploginurl); 
if ($loginp === FALSE) {
    die(curl_error($setuploginurl));
}

curl_close ($setuploginurl); 
var_dump ($loginp);

CURLOPT_SSLVERSION 值必须使用整数值，不是上面列出的字符串

试试这个:

curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2); // constant NOT string value

http://php.net/manual/en/function.curl-setopt.php

value 应该是以下选项参数值的整数:CURLOPT_SSLVERSION

其中之一:

CURL_SSLVERSION_DEFAULT (0)
CURL_SSLVERSION_TLSv1 (1)
CURL_SSLVERSION_SSLv2 (2)
CURL_SSLVERSION_SSLv3 (3)
CURL_SSLVERSION_TLSv1_0 (4)
CURL_SSLVERSION_TLSv1_1 (5)
CURL_SSLVERSION_TLSv1_2 (6)
